General Memory Information
Be sure to unplug the power cable before removing or installing the memory card(s)
or memory modules to avoid damage to them.
Memory cards can be installed in either slot (or both) on the system board, there is
no requirement that one be installed before the other.
It is perfectly acceptable for there to be two partially populated memory cards in the
system, the first memory card does not have to be fully populated before memory on
the second memory card is useable.
Memory modules, on the other hand, must be installed in matched (size and speed)
pairs. Refer to "Memory Card Locations" in chapter 1 for labeling of the memory card
and "Memory Cards" in Removal and Replacement Procedures for instructions on
module removal and installation. A single memory module pair may be installed in
module slots J1 and J2 (not slots J1 and J3). A second memory module pair could
be installed in module slots J5 and J6 (slots J3 and J4 do not have to be populated
first). Along these same lines, there is no requirement that memory module slots J1
and J2 be populated before another slot pair.
Step 1240-1
1. Ensure that the diagnostics and the operating system are shut down.
2. Turn the power off.
3. Remove and re-install any installed memory card(s).
4. Turn the power on.
Does the system stop with a memory checkpoint displayed on the operator
panel?
